Apparatus and method for drawing samples of blood

Abstract

The present invention provides a device for drawing blood from a patient, and methods of drawing blood from a patient using the device. The device comprises holders for collection vials and holders for a luer assembly, and does not require mechanical movement of any part of the device. The device is easy to fabricate, simple to use, and long-lasting.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application relies on the disclosure of and claims the benefit of the filing date of U.S. provisional patent application No. 60 / 774,649, filed 21 Feb. 2006, the entire disclosure of which is hereby incorporated herein in its entirety by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to the field of health care. More specifically, the present invention relates to the process of drawing blood from a patient for clinical analysis, and to devices for use in that process.[0004]2. Description of Related Art[0005]The past thirty years have seen a tremendous increase in the amount of information that can be obtained from blood and blood products. Most importantly among that information is information on the health, both general and specific, of the patient from whom the blood has been taken. For example, a sample of blood may now be analyzed for blood sugar content, which is indicative...

AI Technical Summary

Benefits of technology

[0013]The present invention provides an improved device or apparatus for drawing blood from a patient. The device is relatively simple in design and construction, yet superior to other such devices known in the art in many respects. For example, it is lightweight, streamlined, sturdy, and versatile in its various configurations. It is also relatively inexpensive to fabricate and adaptable. In addition, it provides a convenient and organized means for placement and retention of most or all of the supplies necessary for drawing of blood from a patient, including, but not limited to, secure placement of a luer assembly and secure placement of blood collection vials. It has no mechanical moving parts; therefore, mechanical failures and costly repairs are minimized. The design of the device permits users to know exactly where some or all of their supplies (e.g., vials) are located, allowing quick access to them an minimizing the chance of vials rolling to inaccessible places or falling from trays and shattering. The design also provides support for luers and luer assemblies, allowing quicker and safer inserting and withdrawing of vials. In addition, the device allows for a more streamlined blood drawing process, which results in less chance of needle injury to patients and health care providers. Furthermore, elements of the device can be removably fastened to the device to facilitate removal and replacement if an element becomes worn or broken. Conversely, the present invention relies on the interaction of the practitioner to handle collection vials, which can be an advantage over certain automated systems in that it provides flexibility in implementation by allowing the user to make decisions at the actual point of care as to which vials to fill and in which order, and permits labeling of vials, if desired.

Problems solved by technology

The device, and in particular the base, does not, however, include any mechanical or automated elements that provide mechanical movement for a collection vial, a luer assembly, or any other supply or reagent used in the process of drawing blood from a patient.
